Last Monday, we released the first episode of the Geeks and God Podcast since I became one of the hosts. There were a lot of lessons to be learned in the process. Here are a few of the things I discovered.

A Night of Different Perspectives

A different perspective on choreography

Tonight's rehearsal of our annual musical drama, A Christmas Tale, was a night of different perspectives. I wasn't really thinking when I snapped this photo with my cell phone, but it fits.

When we started out tonight, neither of my lighting guys were there, so I stuck my teenage daughter on the light board, where she did a great job of being mature and attentive, following cues without error. She worked backstage last year, so she saw a new perspective on how lighting tied in to the portions of the show where she'd had to move props on- and off-stage in the dark last year.

Converting Mono to Stereo in Audacity

10/30/2007 in Tech Arts by micah

While mono is perfect for podcasting, some output formats, such as radio or audio CD creation should be produced in stereo. Here are some simple steps to convert mono to stereo when recording in Audacity.

(Note: This process is not going to create a "true" stereo, track. It's really only two-channel mono. See additional notes in the comments below.)

Begin with your mono recording. Select the entire track by pressing Ctrl+A or clicking somewhere in the panel at the left side of the track image.

Simple Podcast Feeds with PHP and the getID3 Library

10/24/2007 in Tech Arts by micah

I may need to come back and write a better introduction to this, but I thought I'd share my relatively simple podcast template.

There are a number of really good ways to deliver podcasts, but a very simple way is to write a simple directory index using php and the getID3 library.

Using Matrix Outputs for Recording and Other Distribution

7/19/2007 in Tech Arts by micah

When we first moved into our current sanctuary in 2001, we set up a wild assortment of connections to feed cassette and CD recording, FM hearing assist, the 70V system for the cry room, and so on. This short-lived arrangement became very cumbersome until we found a good solution that included sensible use of the matrix outputs on our Allen & Heath GL4000 console and the addition of a Rane SM 26B splitter mixer.

Converting Processed Sermon Files to MP3

11/1/2006 in Tech Arts by micah

In the previous article, I explained how to use Audacity to process a recorded sermon to ready it for podcasts and radio broadcast. The resulting WAV file is rather large, and cannot be conveniently stored or streamed, and so it should be converted to MP3 format.

Converting Sermons from CD to WAV for Audacity Processing

10/31/2006 in Tech Arts by micah

We normally record directly from the sound system onto the computer at my church using Audacity, but there are times when the message must be imported from a CD for processing. Recording the audio portion of the CD introduces an extra conversion (from digital to analog and back again) that is not necessary. Instead, it is preferable to retrieve the contents from the audio CD as data. This process is known as CD ripping.

Preparing Sermons for Podcast and Radio

Pastor Tim's sermons are available on the Cornerstone Web site. We now support streaming, download, and podcasts as delivery methods. This page documents the methods used to prepare sermons for the web.

Installing Audacity and Plugins for Sermon and Announcement Processing

10/31/2006 in Tech Arts by micah

Update January 18, 2012: It has come to my attention that Kjaerhus Audio appears to be out of business. I've removed the dead link from the body of the post. Check the comments for more recent links, as it appears the classic plugins used in this tutorial are still available from alternative links. Also, my church no longer uses Audacity a regular basis, so this post is probably a bit outdated.
